Filings & Public Records: Sullivan County Indiana
How to find Indiana energy public records. IURC cause numbers, IDEM Virtual File Cabinet, and county records for Sullivan County energy and data center projects.
Filings & Public Records
There is no single Indiana database that contains every public record for every energy project. Filings are distributed across multiple agencies with different jurisdictions, record formats, and access systems.
Indiana Utility Regulatory Commission (IURC)
The IURC regulates electric utilities, gas utilities, and certain water utilities in Indiana. For energy project tracking, the most relevant process is the declination-of-jurisdiction proceeding under Ind. Code § 8-1-2.5-5. Each proceeding has a Cause Number.
Non-confidential filings are accessible through the IURC Electronic Document System (EDS): iurc.portal.in.gov
Key principle: A declination of jurisdiction does NOT mean no regulation exists. The IURC retains authority over ownership transfers, affiliate transactions, and periodic reporting, and can reinstate jurisdiction if a project fails to proceed.
